HYDROCARBON-BURNER.

SPECIFICATION forming part of Letters Patent No. 779,065, dated January 3, 1905.

Application filed September 20, 1904. Serial No. 225,177.

T0 a/ZZ whom, t may con/cern.'

Be it known that I, HARRY F. BLANCHARD, acitizen of the United States, residing at Somerville, in the county of Middlesex and State of Massachusetts, have invented new and -useful Improvements in Hydrocarbon-Burners, of which the following' is a specification.

This invention relates to certain new and useful improvements in that class of devices now generally known as hydrocarbon-burners and wherein a more or less heavy hydrocarbon is vaporized and the resultant gas is mixed with air and the combined vapors utilized for illuminating or heating purposes; and my invention consists of the parts and the constructions,arrangements,and combinations of parts, which I will hereinafter describe and claim.

In the accompanying drawings, forming a part of this specilication, and in which similar characters of reference indicate like parts throughout the several views, Figure 1 is a vertical sectional view of a hydrocarbonburner embodying my invention. Figs. 2 and 3 are side elevations. Fig. A is a plan view of the burner. Fig. 5 is an enlarged section on the line I I of Fig. l. Fig.- 6 is a section of the vaporizer-section detached. Fig. 7 is a cross-section on the line D D of Fig. l.

In carrying out my inventionI may use the same in connection with a tank or reservoir, (notshown,) from which leads a pipe 45, by which oil from the tank is supplied to the burner, said pipe being fitted to the lower base-section' or starting heater portion 2 of the burner, which comprises a separate casting, with air and oil passages and controlling means which I will hereinafter describe.

AXially through the base or casting 2 is made an oil-passage c, which forms, substantially, a prolongation of the oil-supply tube, said casting having also in its lower portion alateral passage b and circumferential air-inlets e, said lateral passage being controlled by a valve 5, having a threaded shank and an operating milled head or wheel, by which it may be adjusted in and out to regulate and control the oil, which Vmay be allowed to flow through the passage to a channel c, leading to an annular channel el, formed inthe lower portion of the base or casting 2.

The annular channel cZ- is at the base of a trough or cup formed by two vertically-disposed concentric rings R, in which trough is placed a wick of asbestos or other absorbent, incombustible, and indestructible material, which is designed to be saturated by the feed of oil through the oil-passage ct and its branch b and the passages c and (l.

The central portion of the base or casting extends some distance above the trough and is of reduced diameter, so as to provide `an annular air-space with which the air-inlets e communicate, and the upper end of the reduced central portion has a threaded nipple adapted to be fitted to a companion member on the middle or vaporizer section, the construction and operation of which I will presently describe.

Surmounting the burner-trough is a chimney formed of concentric rings 7 and 8, of foraminous material or of material provided with numerous holes for the admission of air, which is derived both from the outside and from the interior air-space which surrounds the central portion or stem of the base or casting 2 and which air freely mingles with the vapors arising from the wick in the trough, and thereby promotes the combustion of the oil and insures the necessary heat for vaporizing the oil in the superposed vaporizingchamber. v

In order to facilitate the ignition of the wick, an opening is made in the outer chimney-ring 7 for the insertion of a lighted match or taper, which opening is normally closed by the plate extension of a lever or linger-piece 9, pivoted at 10 and backed by an appropriate spring, a's at 46, fixed to the base and having its free end pressing against the heel of the lever or finger-piece. The pressure of the finger upon this lever will depress the spring and allow the lever to rock about its pivotal connection and uncover the match-opening, and when the pressure upon the lever is released the spring will close the plate eXtension of the lever against said opening, so that it will serve as a closure therefor.

' a suitable pressure that may be given to it iiow through the passages a and g into the vaporiZing-chamber f, where it is converted into vapor by the heat from theA startingburner formed by the wick and chimney, which are below and deliver the heat directly against the bottom ofthe vaporizing-chamber, as shown'in Fig. 1, said vaporizer-section 11 having an apron or flange 11u surrounding the upper part of the chimney 7 8 to better cony centrate the heat from thel'atter against the bottom of the chamber j.

The vaporizing section is somewhat enlarged at the base, and it forms a casing around the valve mechanism, gas-chamber, and vaporiZing-chamber, to which latter the oil is led by the passage g, (which is inclined, as shown in Fig. 6,) a lateral channel p, and a vertical passage o, leading downward through the top of the chamber.

A threaded valve 28 is appropriately mounted in a seat in the vaporizer-casing, and this valve controls the flow of oil from the passage g to the lateral passage p, from which it iiows to the aforesaid passage 0 into the vaporizingchamber.

To facilitate the cleansing of the passages 0 and p, a screw or other plug 30 is removably fitted in the casing inline with the passage o, as shown in Fig. 3.

The valve 28 carries a worm 32, which rotates with the stem, but is splined thereto, so that the valve may move longitudinally relative to the worm, and the said stem passes through a threaded bushing or plug 31 to the outside ofthe vaporizer-'casing, Where it is provided with a milled head or wheel, by which it may be operated to control the passage of oil to the vaporizing-chamber.

Arranged in the vaporiZer-casing at right angles to the needle-valve 32 is a gudgeon or pin 16, on which is turnably mounted a mutilated gear or segmental pinion 12, which is in mesh with the worm 32 on the stem of the valve 28, said gudgeon or pin having one end mounted ina bearing in the casing and the opposite end mounted in a plug 29, as shown in Fig. 7.

The segmental pinion is employed to operate a needle 15, and for this purpose it engages a rack-bar 13, having upper andlower stems 14, working in suitable vertical guides 14', formed in the vaporizer-casing, said upper stem having the needle 15 xed to it and adapted to work through and maintain clean a small gas-outlet 7c in a plate 18, which is Set flush with the top of a threaded nipple 17, screwed into'the open top of the vaporizercasing and which,with said plate 18,closes said top, said nipple carrying the upper guide 14l and having suitable passages j for the flow of gas from the gas-chamber z' to the aforesaid hole or gas-outlet 7c.

Over the plate 18 and threaded plug 17 and screwing upon the upper end of the casing is a cap 34, having lateral air-ports r, to which cap the stem portion of the upper burner-casing 35 is fitted and which burner-casing in this instance is of shallow circular form and has an annular vaporiZing-cham'ber w around its rim, which communicates with agas-chamber I at one side.

A pipe 48 connects the vaporiZing-cham'ber f with the vaporizing-chamber w of the burner and leads the gas from the former tothe latter, while a second pipe 49 connects the gaschamber I of the burner with the internal gaschamber of the chamber t', the connection be'- ing by threaded pipes and unions, as shown at 51, and adiaphragm or partition 50", Fig. 5, forms two separated pockets Y Y', tothe former of which gas enters from the pipe 48, while from the latter the pipe 49 conducts the gas to the chamberv f.

lithin the burner-casting, which, as before stated, is of circular form and is recessed on top, are placed the rings or plates 36,- 37, and 38, held together and to the casting by means` of screws 44 or equivalent means. In or between the plates or rings 3'6 37 and the burnercasting are formed radial channels Z, which communicate with annular channels a', with radial branches c leading to appropriate gasburner outlets around the edges ot the plates.

In the stem of the burner-casing isfslidably mounted a tubular valve 39, whose lower open end receives the gas from` the chamberz' with the admixture of air from the ports r, said valve having its upper end adapted to enter openings in the center of the plates 36 and 37 to open or close the gas-passage of the valve,

with the radial passages beneath any one or more of the burner-plates, according asmore or less heat is desired for cooking purposes. The top of the valve has radial outlets whichv deliver the gas into the radial passages Z,and said valve has teeth upon its side formi-ng a rack-bar with which engages a pinion 4O,whose4 matter of a separate application liled by me of even date herewith and wherein the operation of said parts is set forth in detail and is substantially identical with the operation of corresponding parts of this application, the essential differencebetween the two applications being in the construction and operation of the burner of this application and which burner is designed primarily for cooking and heating purposes.

Having thus described my invention, what I claim as new,'and desire to secure by Letters Patent, is4
